54<h2>Return Values</h2>
55<p>
56The result codes that may be returned by <code>NANDOpenAsync</code> are listed below. Returns <CODE>NAND_RESULT_OK</CODE> when the request begins normally.
57<p>
58<code>NAND_RESULT_OK<br> NAND_RESULT_ACCESS<br> NAND_RESULT_ALLOC_FAILED<br> NAND_RESULT_BUSY<br> NAND_RESULT_INVALID<br> NAND_RESULT_FATAL_ERROR<br></code>

63<p>
64<code>NAND_RESULT_OK<br> NAND_RESULT_ACCESS<br> NAND_RESULT_INVALID<br> NAND_RESULT_MAXFD<br> NAND_RESULT_NOEXISTS<br> NAND_RESULT_UNKNOWN<br> NAND_RESULT_FATAL_ERROR<br></code>

68<H2>Description</H2>
69<p>
70Asynchronously opens a file. Proper access rights are required to open a file. You can't open files if you don't have permission to access those files. <code>NAND_RESULT_BUSY</code> is returned and this function call is denied when the queue for accepting requests inside the library is full.
